Application led March 20, i911. Serial No 615,703.

To all whom it may concern Be it known that is, CHARLES DE LUnAosnvrcs,a citizen of the United States, residing at New York, in the`county ofNew York and State of New York, have invented new andl usefulimprovements in Siphon-Heads, of which the following is a specification.Y

This' invention relates to vimprmements .in siphon heads and its objectis to provide a construction embodying certain 'new details of structureand arrangement for the poses of securing an absolutely tight tlt ot theheadupon the bottle, andof preventing any escape of gas through theinterstices bef tween the related parts or through the pores of thehead.

ln carrying out the foregoing' object. and purposes the inventionproposes an improved retaining connection between vthe head and thebottle neck; an improved sealing' `gasket between said head and neck;novel and improved relations between the gasketand the parts appartenantthereto: an improved valve seat construction; and certain other featuresof detail improvement to be specifically set forth.

A preferred embodiment ot' the invention is illustrated in theaccompanying drawings, Where-in- Fin'ure l is a vertical centralsect-ion of a Siphon head in accordance with the invena section on theline .Li-n of l; Fig'. 3 shows/in section and in group relation thevalve and its appurtenances; Fig. ll is a sectional detail showing' thehead construction, the clamping device being' omitted; 5 is a' sectionalvien' of the improved sealing gasket; 'Figi'. 6 is a section on the liucli-B ot' Figi'. Li: Fig. 7 is a sectional detail showing the head iittedwith one of the members` ol the clamping" device; and lfig'. S is anenlarged sectional detail showing' the improved valve seat consocket andthe top of the neck an improved sealing gaske 6 is litted.

rthe nie-ans ror securing a tight tit of the' hea-d upon the neckembodies a neck ring 7 and a head ri ig 8,' these elements beingcompanions. ln prior const-motions the socket is provided with moldedthreads and the threaded'nefk ring' engages directly with the threadsat" the socket. lVhere the head is of vitreous iaterial, and especiallyin the case oi" porcelain, the threads in the socket are irregular andfrequently, when the neck ring is engaged therewith, the socket iscaused to crack. The irregularity or the threads in the. socket iscaused by the changes in form incident to baking, and the cracking ofthe socket is due to the fact that the neck ring', when it is engagedwith said threads, Will, on account of 'their irregularities,producc'expansion at different points, the cracking` obviously resultingfrom such expansion. It will be apparent, therefore, that theirregularity of the thJe-ads, even when the socket does not crack, willprevent an absolutely tight and eliicient connection between the Siphonhead and the bottle neck. One of the purposes ot the presentimprovements is to avoid the objection stated and in carrying out thispurpose the companion rings 7 and S aforesaid are employed. The ring 8is oi. soft metal and is permanently associated with the socket Toestablish this association the socket has threads 9 originally moldedtherein which threads are flat, shallow and of considerable extent. The,ring,r 8 is thereupon cast in the socket and its metal fills atentedInlay i3, ittin the spaces between Jthe threads 9 so thatI threads .0are formed in the outer surface of said ring. which are in exactconformity to and securely grip the threads 9. permanent and strontTintercngagement of the Vthreads 9 and l() is thus established and suchirregularities as may occur in the threads 9 are manifestly of advantagein securingr p erinanency between the socket 5 and the ring 8. Thelatter is provided on'its inner face with .threads l1 which correspondt0 the threads on the ringr 7. lt will be apparent that-the provision ofthe rings 7 and 8.1n conjunction with the manner of assoclatmg the ringS and thesocket 5 is of decisive advantage in that it. promotes a secureand tinhtfengragemeut ot said socket upon the neck Q.

The gasket is provided with an axial opening 12 and with acircuniscribing fiange 13. The portions of the gasket at each side ofthe flange are of frusto-conical outline and for convenience may betermed bosses, as such being designated by the numerals 14 and 15respectively. rilhe upper boss 14 is provided with an annular flange 16which overhangs the opening 12 and delines a constricted extension 17 ofsaid opening. The si hon tube is indicated by the numeralv 18 mili itsupper portion is fitted inthe opening 12. The lower boss-15 fits intothe opening of the bottleneck. ThisI opening, as previously Stated, isof fia'ring' outline and consequently the boss 15 is wedged, so tospeak, between the inclosed portion of the tube 18 and the adjacentsurface of the bottle neck. The boss 15 is, on account of its wedging`tit just referred to, instrumental.insecurely sealing the mouth of thebottle and the flange 13 performs a like function in connection withtheupper face of the bottle and the adjacent face of the socket Inaddition to its function asa positive seal, the gasket 6 has the furtherfunction of serving as an elastic and yieldable securing means for thetube 18 which., as stated, has its upper portion fitted inthe opening12. 1n connection with this latter function the gasket is of advantagein absorbing jars and vibrationsand in thereby preventing the tube 18from being easily broken.

. The head 4 is provided with an axial duct 19 and with a curved liquiddischarge duct 20 extending;r at an angle from the duct 19. Below theduct 19 said head is provided with an axially disposed valve chamber'21,

and between the valve chamber 21 and the socket 5 with a coniformopening 22 in which the boss 14 conformably seats. The wall of the valvechamber 21 is formed with longitudinal ribs 23 which not only center thevalves 24 but bear against the upper face of the boss 14 immediatelyadjacent the fiange 16 and thereby serve as a substantial reinforcementfor the latter, it be ing lunderstood that the purpose of the flange 16is to prevent u ward displacement ofthe tube 18 and to a ord'an elasticcushion against which the upper end of said tube seats. I

The valve 24 consists'of a cylindrical rubber plug which has a conicalseating end and is normally held against a seat 25 formed between theduct 19 and the valve chamber 21 and shown in detail in Fig. 8. Thesea't 25 is of conical outline and is pro vided With two or morecomparatively sharp annular ribs which sink into the material of thevalve and are thus effective, when the valve is in its closed position`to establish an efficient seal against the escape of gas through theduct 19. The valve seat 25 is ribbed because porcelain is porous and itssurface is vnot of uniform character. Con- `isequently the provision ofthe ribs on the The valve 24 is carried by a stem 26l which projectsaxially through the duct 19 aand beyond the upper end of the head. The

stem 26 is formed at a distance from its lower end with a dished flange27 against which the valve 24 is tightly held, and below the flange 27with comparatively sharp threads 28. The threaded portion 28l of the'stem 2G passes through an axial opening 29 in the valve 24. This openingis originally of smaller diameter than the said threaded portion 28and'` consequently the' latter is utilized to cut its own threads in theopening 29, and to thus provide for a secure fastening Vof the valve. Anut 30 is fitted upon the lower end of the valve stem and adds to thesecurity of the valve.

The stem 26 carries on its upper end a button 31 which works in a recess32 formed in the upper end of the head 4. Owing to the provision of theribs on the valve seat 25 it is essential to prevent the valve 24 fromturning` and for this purpose the brtton 31 is formed with longitudinalgrooves to receive corresponding projections 33 onthe Wall of the recess32.

The valve 24 is held to its seat by a spring which is fitted in a recess36 of the button 31 and which bears at one end against said button andat its other end againsta Washer 37. gasket 38 which snugly surroundsthe valve stem 26 and is fitted in a reduced coniforin extension of therecess 32, resting on a web or ledge 39 which separates said recess fromthe duct 1,9 and which is provided With an opening conforming` to thediameter of the' stem 2G and through which said stem passes. The spring35 is of sufiicient strength to hold the valve 24 firmly to its seat andat the same time to put such pressure on the gasket- 38 as will causethe latter to hug` the valve stem and thereby prevent any Iiras fromescaping through the opening in the ledge 39.
